  • the wet section 1 comprises a former and a press section.
  • the former has a headbox 4, an inner, carrying forming clothing 5, an outer, covering forming clothing 6, a forming roll 7 and a breast roll 8.
  • the forming roll 7 and the breast roll 8 are arranged in proximity to each other so that the two forming clothings 5 , 6 run together on the forming roll 7 whilst defining a wedge-shaped gap between them before they run together, the headbox 4 delivering a single- or multi-layer jet of stock into said gap to form a paper web 9 by way of the stock being dewatered.
  • the two forming clothings 5, 6 run together over the forming roll 7 and then in individual loops over a plurality of rolls 10 arranged to move, guide, align and stretch the forming clothings 5, 6.
  • the press section comprises a roll press 11, consisting of a first press roll 12 and a second press roll 13, which press rolls 12, 13 define a press nip between them.
  • the press section has only one press, i.e. roll press, as shown in the drawings, so that no additional press nip is formed against the second press roll 13 or against the first press roll 12 or defined by any two other press elements.
  • the press section has a press felt 14, running through the press nip and in a loop around a plurality of rolls 15, arranged to move, guide, align and stretch the press felt 14.
  • Devices (not shown) for cleaning the press felt 14 are located after the press nip.
  • a suction device 16 which, in the embodiment shown, consists of a suction roll that is arranged just before the press nip and from which the press felt 14 carries the web 9 so that the side of the web 9 facing away from the felt is free from contact with any structural element before the press nip.
  • the suction device 16, which has a curved suction zone 3, is so arranged in relation to the nearest upstream guide roll
  • the wrap angle should be at least 100°, preferably at least 110°. In experiments performed with a suction roll, the wrap angle has been about 140°.
  • the suction zone 3 encloses a sector angle corresponding to said wrap angle and extends within the same. The large wrap angle contributes to increased dewatering.
  • 16 is arranged to provide the paper web 9 with a dry-solids content of at least 15 per cent, preferably at least 20 per cent and most preferably at least 25 per cent.
  • the drying section 2 comprises a crowned drying cylinder
  • the drying cylinder 17 having a relatively large diameter and a polished envelope surface.
  • the paper web is creped away from the drying cylinder 17 with the aid of a crepe doctor 19 to obtain desired creping, whereupon the finished creped paper web 9' is reeled onto a reel (not shown) .
  • the drying cylinder 17 also forms said second press roll 13 in the roll press 11 of the drying section 2.
  • Said suction roll 16 is arranged at a distance from the drying cylinder 17 so that no press nip is formed between them and so that the web 9 does not come into contact with the envelope surface of the drying cylinder 17 until it reaches the press nip or immediately before.
  • the inner carrying forming clothing 5 consists of a forming felt, the loop of which is extended to the press section 2 so that it also acts as said press felt 14.
  • the inner carrying forming clothing 5 consists of a forming wire, the loop of which encounters the loop of the press felt 14 in a transfer zone 20 for transferring the web 9 to the press felt 14, a suction shoe 21 being arranged within said transfer zone 20 in the loop of the press felt 14.
  • the first press roll 12 of the roll press 11 consists of a press roll 12a with a solid shell 22 that can be smooth, grooved or blind-drilled.
  • the press roll 12a can be straight depending on the crown of the drying cylinder 13, amongst other things, but is preferably crowned so that it has a crown curve corresponding to a certain compression pressure to obtain profiles for compression-pressure and dry-solids content that are as uniform as possible after pressing without zones with higher moisture occurring in the web after the press nip.
  • the first press roll 12 of the roll press 11 consists of a suction press roll 12b that can be straight depending on the crown of the drying cylinder, amongst other things, but which is preferably crowned so that it has a crown curve corresponding to a certain compression pressure to obtain profiles for compression-pressure and dry-solids content that are as uniform as possible without zones with higher moisture occurring in the web after the press nip.
  • a special advantage of the suction press roll 12b is that it also has a cleaning effect on the press felt 14 so that special cleaning means arranged after the press nip can be completely or partly reduced and the frequency of felt replacements can be diminished.
  • the first press roll 12 of the roll press 11 consists of a variable crown press roll 12c, the shell of which can be smooth, grooved or blind-drilled.
  • the crown curve of the press roll 12c can be changed during operation to be adapted to a pre-determined compression pressure so that as uniform as possible profiles for compression-pressure and dry-solids content are obtained without zones with higher moisture occurring in the web after the press nip . If the machine is to manufacture a soft crepe paper of a different desired grade with respect to bulk and strength, the crown curve is changed to correspond to a new compression pressure so that as uniform as possible profiles for compression-pressure and dry-solids content for the new setting are obtained without zones with higher moisture occurring in the web after the press nip.
  • Figure 3a shows schematically a longitudinal section of one of the end portions of the variable crown press roll 12c, the shell 22 of which surrounds an upper pressure chamber 23, connected to a pressure source (not shown) .
  • the pressure chamber 23 extends between the end walls 24 of the press roll, the ends of the shell 22 being rigidly attached to said end walls. Changing the pressure in the pressure chamber 23 produces a corresponding change of the crown curve within the press nip.
  • the shell 22 also surrounds a lower pressure chamber 25 having a pre-determined lower pressure than the upper pressure chamber 23.
  • the pressure chambers are separated by opposite, axial sliding sealings 26.
  • the first press roll 12 of the roll press 11 consists of a zone-controllable, variable crown press roll 12d, the shell 22 of which can be smooth, grooved or blind-drilled.
  • the crown curve of the press roll 12d can be changed during operation to be adapted to a pre-determined compression pressure so that as uniform as possible profiles for compression-pressure and dry-solids content are obtained without zones with higher moisture occurring in the web after the press nip.
  • the crown curve is changed to correspond to a new compression pressure so that as uniform as possible profiles for compression-pressure and dry-solids content for the new setting are obtained without zones with higher moisture occurring in the web after the press nip.
  • the crown curve can additionally be influenced zone by zone so as thereby to adjust the compression-pressure profile within the corresponding parts so that the same becomes even more uniform and straight than is possible with a variable crown press roll that is not zone-controllable to obtain a dry-solids content profile after the press nip that is correspondingly more uniform and straight.
  • Figure 4a shows schematically a longitudinal section of the zone-controllable, variable crown press roll 12d, which has an axial row of pressing members 27 equidistantly arranged inside the shell 22 and opposite to the press nip.
  • the pressing members 27 are divided into two outer groups 28, 29 and an inner or intermediate group 30 between them, the groups 28, 29, 30 of pressing members 27 being actuated independently of each other via ⁇ to to ⁇ > ⁇ i o L ⁇ o L ⁇ O L ⁇
